This study reports the preparation and characterization of Polybutylene Succinate (PBS)-Polycaprolactone (PCL) melt blends (10-40 wt.% PCL) in the presence of a compatibilizer, in order to explore their potential use as a biomaterial. The thermal transitions, as well as the crystallinity of the polymer blends were analyzed by Differential Scanning Calorimetry, the thermomechanical properties were analyzed via Dynamic Mechanical Analysis and phase morphologies were characterized by Scanning Electron Microscopy. Degradation profiles of the blends were analyzed in PBS buffer solution at pH 7.4 at 37 degrees C via pH measurements. Cytotoxicity of the PBS/PCL films were tested by MTS assay.


Flow induced polymer-filler interactions: Bound polymer properties and bound polymer-free polymer phase separation and subsequent phase inversion during mixing
Akay, G. (Wiley, 1990-11)
The irreversible absorption of macromolecules on to solid filler particles during mixing in the melt is investigated. The molecular weight and concentration dependence of the absorbed layer thickness are evaluated and the chemical and morphological nature of the irreversibly absorbed polymer (bound polymer) are determined. It is found that the thickness of the bound polymer is not only dependent on the filler concentration but also dependent on polymer molecular weight. Bound polymer in high density polyeth...

The effect of temperature and soluble solids on nonenzymatic browning in clarified and concentrated apple juice was analyzed by response surface methodology. Color development at 20, 40 and 60 Brix and temperatures ranging from 70-90C were compared over a time range of 30-180 min. The browning reaction was found to be dependent on soluble solid content as well as on the reaction conditions such as temperature and time. The model combines the effect of temperature, soluble solids content and time on color ch...
Polystyrene-organoclay nanocomposites prepared by melt intercalation, in situ, and Masterbatch methods
Yılmazer, Ülkü; Ozden, G (Wiley, 2006-06-01)
In this study, polystyrene (PS)/montmorillonite nanocomposites were prepared by melt intercalation, in situ polymerization, and masterbatch methods. In the masterbatch method, as the first step, a high clay content composite of PS-organoclay (masterbatch) was prepared by in situ polymerization, and then the prepared masterbatch was diluted to desired compositions with commercial PS in a twin-screw extruder. The structure and mechanical properties of the nanocomposites were examined. X-ray diffraction (XRD) ...
Interfacial Interactions and Flammability of Flame-Retarded and Short Fiber-Reinforced Polyamides

Interfacial properties, crystallinity and flammability of short fiber reinforced and flame retarded polyamide 6 and polyamide 66 compounds are investigated, emphasizing the influence of flame retardant fillers on the resistance of fiber/matrix interface to shear. Interfacial shear strengths are derived through a micromechanical approach by determining the tensile properties and residual fiber length distributions. Validated by fracture morphologies, interfacial strengths are found to be governed by filler-i...
Trimethylene Carbonate and epsilon-Caprolactone Based (co)Polymer Networks: Mechanical Properties and Enzymatic Degradation
Bat, Erhan; Harmsen, Martin C.; van Luyn, Marja J. A.; Zhang, Zheng; Grijpma, Dirk W.; Feijen, Jan (American Chemical Society (ACS), 2008-11-01)
High molecular weight trimethylene carbonate (TMC) and epsilon-caprolactone (CL) (co)polymers were synthesized. Melt pressed (co)polymer films were cross-linked by gamma irradiation (25 kGy or 50 kGy) in vacuum, yielding gel fractions of up to 70%. The effects of copolymer composition and irradiation dose on the cytotoxicity, surface properties, degradation behavior, and mechanical and thermal properties of these (co)polymers and networks were investigated. Upon incubation with cell culture medium containin...
